Headrest bubbling and other issues, theories and testing

Hey everyone!
Joel here, I have a Tesla Model 3, and have driven about 30000 miles on it, and over the past 10000 miles I have noticed that my headrest has started to bubble. I don't use any hair product.
Now I have some theories, that I want to propose. If anyone else has this issue, please let me know if any of these factors are true for you:
I wear glasses
I used anti dandruff shampoo (Head and Shoulders, or Nizoral shampoo )
I live in the Bay Area and park in a carport
I drive a lot, with my head actually against the headrest.


One theory I have is that the light is being amplified by the side mirror causing the melting of the vinyl. This could be the case given that the side mirrors are angled to be focused on the head rest(so I can see them when I drive). But a counter is they fold in when I park.

Another theory is my glasses are amplifying the light... but my head is in the way.


My last theory is that perhaps I am not getting all of the shampoo out of my hair, and that, that possibly some residue is causing it. Though I have heard of people who were bald having the issues, so I don't know...

Any other thoughts? does anyone else have this issues also do the following above?

You can see a photo I took when I first noticed it(June), and a photo of it recently(September)

So, if they are going to say it isn't faulty materials or workmanship, what are they saying it is?

And what service centers, do I know never to go to them?

they are saying its chemical, and likely from hair product, so its technically not under warranty. its the Sunnyvale and Seaside one. that said, other than that issue, they have been very generous in service. (free tire rotations). my mobile tech is also amazing, and has done so much to help.
 
there's a DIY on how to bend the headrest so that it isn't so far forward. part of the DIY is to remove the cover from the padding. in the DIY, there is no evidence that the cover is glued to the padding.


can someone remove their cover from the padding to determine if this is solely the cover or the padding that's the problem here?

so its not the glue then... I mean, all the material must be there, so if I were to undue the head rest and pull the material taught, would that in theory fix it?
 
honestly i don't blame tesla. this is a weird case and not evident of manufacturer defect. unless OP can open up the cover and find something underneath that has caused all of this, there has to be a logical reason as to why the material bubbled the way it did.

to me, it looks like either chemical burn, heat, or a combination of the two. fabric/rubber/poly materials don't just "bubble" unless they interact with something. my guess is a petroleum-based product came in contact with the headrests, but OP swears this is not the case.

That could be possible I am looking into the ingredients in my cleaners and I think one of them includes petroleum... Would you say this is likely the cause?
